Möttau is a village (Ortsteil) of the municipality of Weilmünster in the district of Limburg-Weilburg in central Hesse.

Neighboring towns are Weilmünster (southwest), Altenkirchen (north), Kraftsolms (east), and Dietenhausen (southeast).

The place is mentioned for the first time in a donation deed from the Codex Eberhardi in the Fulda monastery.

The document states that Frederick gave the Mitie estate (Möttau) to St. Boniface.

It was pledged to the provost of Gemünden on June 23, 1326, and fell to Count Gerlach of Nassau in November of the same year.

In the course of the territorial reform in Hesse, on 31 December 1970 the former market town of Weilmünster in the Oberlahn district merged voluntarily with the previously independent municipalities of Aulenhausen, Dietenhausen, Ernsthausen, Laimbach, Langenbach, Laubuseschbach, Lützendorf, Möttau, Rohnstadt and Wolfenhausen to form the new enlarged municipality of Weilmünster.
